Okay, I think I see what you're saying now. I agree that it makes sense when you time it so that it's your turn to go through. Do people really react well to this? I don't have a lot of experience with the idea of timing it, it seems like people would just see another cyclist blowing a stop sign (when in fact you were going on your turn, but it looks like you just happened to roll through when you saw a gap in the traffic flow (which there would have been, if you were a car, but they aren't expecting there to be, because you're on a bicycle).
Sheesh, this is a tricky subject. Maybe we should invent a "me next" hand signal or something (when you're approaching the intersection, point at the person you're going to enter the intersection after or something). I'm just brainstorming.
EDIT: Realized more pointing wasn't going to help, since we point for turns. Rrrrr.
